Hi all, just created an account. I found this in my yard today. Can anyone identify what this is? The led flashed once. It is mounted on that roughly 1/4" board and stuck on a white round "pillow". Any thoughts as to what this is?

While I was walking down the beach one bright and sunny day
I saw a great big wooden box a-floatin' in the bay
I pulled it in and opened it up and much to my surprise
Ooh, I discovered a boom-boom-boom, right before my eyes

And than I took it home with me to give it to my wife
But this is what she hollered at me as I walked in the door
Oh, get outta here with that boom-boom-boom, and don't come back no more
Max.

The PCB looks like a typical solar garden light - it probably flashed when you cast a shadow over the solar panel, they sense the current from that to turn the LED off during daylight.

Some types have a colour changing LED that needs 4V - you could probably use the inverter to charge a supercapacitor to run a few TTL chips for short periods.

That's an odd configuration but otherwise looks just like a solar garden light as noted. Ask your neighbors. I've had some of my lights vandalized at night. Teenagers of whoever are drawn to the light like moths and kick them across my yard. This object may have come from a neighbor's yard.

That looks like an improvised, inexpensive device to signal a location to someone. Perhaps where to drop off the drugs. Long ago in my family history, one of my relatives threw cans of opium into yards that were marked with the secret code...
